Abstract

This invention relates to earth moving machines. The goal is to increase the versatility, accuracy of installation operations and performance. The working equipment includes a handle 1, a bucket 4 of two jaws, placed between the handle 1 and a bucket 4, a double hinge insert 5, a lower hinge 6, hydraulic cylinders for controlling the jaw of a bucket 4 and a double hinge insert 5. The bucket is made in the form of a thin-walled shell in the shape of an ellipsoid surface bounded by two mutually perpendicular secant planes, which are planes of its longitudinal symmetry, and each jaw is formed by a secant plane along the plane of symmetry of the bucket 4, perpendicular to the first two. Each jaw of the bucket 4 is provided with an upper wall with an opening for attachment to the lower hinge 6 of the double-hinge insert 5. The lower parts of the jaws are hingedly connected to each other. By means of hydraulic cylinders, the bucket 4 can be turned to the “right shovel” or “back shovel” position. Jaw mi can grab and move piece goods. 4 il.

1 hinge insert 5, lower hinge 6, hydraulic cylinders controlling the jaws of the bucket 4 and double-hinge insert 5. The bucket is made in the form of a thin-walled shell in the form of ellipsoid surfaces bounded by the wedge of mutually perpendicular cutting planes, it is ush, its planes are its longitudinal symmetry and each jaw is formed by a secant plane along the plane of symmetry of the bucket 4, perpendicular to the first two. Each jaw of the bucket 4 is provided with an upper wall with a hole for connection to the lower hinge 6 of the double-hinge insert 5. The lower parts of the jaws are hingedly connected to each other. By hydraulic cylinders, the bucket 4 can be turned to the “right shovel or back shovel” position. Jaw mi can grab and move piece goods. 4 il.

The invention relates to earth-moving machines, in particular, to working equipment of single-bucket hydraulic excavators.

The purpose of the invention is to increase the versatility, accuracy of installation operations and performance.

FIG. Figure 1 shows the working equipment of the excavator; in fig. 2 is a view A of FIG. one; in fig. 3 - possible positions of the jaws of the bucket; in fig. 4 - the same.

The working equipment of the excavator includes a handle 1 consisting of two jaws of the first 2 and second 3 buckets 4, placed between the handle 1 and the bucket 4, a double-hinge insert 5, the lower hinge 6, which is connected to the bucket 4. The hydraulic cylinder 7 rotates the double-hinge insert 5 in the longitudinal plane is pivotally attached to the double-hinged box 5 and the handgrip 1. The hydraulic cylinder 8 rotating bucket 4 pivotally attached to the first jaw 2 and a double-hinged box 5. Cylinder 9 jaws pivotally secured at one end to the second jaw 3 and the second end is pivotally cr The double-hinge insert 5 or the first jaw 2. The double-hinge insert is connected to the arm by the hinge 10. The bucket 4 is made in the form of a thin-walled shell in the form of ellipsoid surfaces bounded by two mutually perpendicular intersecting planes, which are planes of its longitudinal symmetry, and each the jaw is formed by the secant plane along the plane of symmetry of the bucket, perpendicular to the first two.

Each bucket jaw is provided with an upper wall 11 with a hole for attachment to the lower hinge 6 of a double-hinge insert. The lower parts of the jaws are connected by a hinge. When attaching the hydraulic cylinder 9 to the double-hinged insert 5 (Fig. 1), it is convenient to work with the jaw as a grab or to grab various objects, and also to work with one jaw 3 as a backsplash, when

This jaw 2 is motionless. Jaws 2 and 3 can be provided with teeth 12.

Working equipment of the excavator works as follows.

Hydraulic cylinder 8 and hydraulic cylinder 9

the jaws of the bucket 4 can be rotated at a certain angle, but less than 180 °.

Using hydraulic cylinders 8 and 9, you can turn the jaws 2 and 3 around the hinge 7 by 90 °, and in this case the bucket 4 from the position of the shovel locks its position to the right shovel (Fig. 3). The intermediate position of the jaws of the bucket 2 and 3 is shown in FIG. 3 and 4, while the jaws 2 and 3 are located at angles of the wasps, and ot or ot and about relative to the longitudinal plane. With the same speed over time of the hydraulic cylinders 8 and 9, a symmetrical installation of the jaws 2 is achieved.

and 3 relative to the longitudinal plane of ° C

  (.,. The jaws can be equipped with teeth 12 (in Fig. 2). Bucket 4. Can work as a grab, while the jaws 2

 and 3 can be rotated at arbitrary angles.

The advantage of the present invention is the ability to pick up and shift objects that are arbitrarily placed in space, to make a quick changeover of the bucket from the position of the shovel to the position of the back shovel and vice versa. If necessary, the bucket can dig to the side or dig with one jaw. All this increases the versatility of the working equipment of the excavator performance.
